GUIDING DEVICE FOR WHEELED AGRICULTURAL IMPLEMENTS.

No. smears.

'implements and particularly contemplates the provision of a simple andinexpensive arrangement for a ready guidance ofthe machine, and whichmay be readily actuated by the operator from his seat upon the machine.

My invention further and specifically resides in the following featuresof construction, arrangement and operation as will behereinafterdescribed with reference to the accompanying drawing, forming a part ofthis specification, in which like numerals are-uscd to designate likearts throughout the several figures, and in w iich .Figurel is anelevation of my improved guiding device illustrating its attachment to aa frame, car in an o erators seat Fi 2 is a top plan view of the same,the seat having been broken away, Fig. 3- 1s a detail sectional viewlllustratmg the upper bearing of thevert1- cal shaft carrying a guidewheel at its lower end, and Fig. 4 is a detail sectional viewillustrating the lower bearing of the vertical shaft.

In the practical embodiment of my invention I provide a guiding wheel 1comprising an enlarged hub portion 2, a circular cutting disk 3extending centrally from said hub I portion and adapted to'cut throughthe soil and to allow the hub portion 2 to travel upon the surfacethereof. The guiding wheel 1 is journaled within. the lower openfreeends of' the caster forks 4. rigidly secured at their upper ends to avertical shaft 5. The shaft 5 is preferably secured within the frame ofthe wheeled agricultural implement, and I have'shown the samerotati-vely mounted at its upper end to bracket 6 secured to and extheframe.

tending from a central bar A of a wheeled frame, upon which is alsomounted a seat B. The shaft 5 is further supported to rotate freelywithin the socket 7 carried by a slant- Y ed supporting rod 8 attachedat its upper end upon the under side of said central bar A of Thevertical shaft 5 is further Specification of Letters IPatent.

provided at its upper end .above the bracket 6 with a squared portion 9upon which is located a transversely extending lever 10 having a squaredopening therethrough centrally of itsends, adapted to fit about saidsquared portion 9 of the shaft 5 to rotate-the same when said lever isoscillated, said shaft 5 being threaded above saidlever 10 and adaptedto receive a nut 11 thereon to hold the same in place. The secondoscillatory lever 12 is pivoted centrally beneath the central bar A andis provided with extensions 13 therefrom on which the operators feetrestwhen said operator is sitting upon seat B. Levers 10 and 12 areconnected by means of the connecting rods 14 extending therebetweenparallel and on each-side of the central bar A and adapted to transmitmovement from the foot lever 12 to oscillate the lever 10 and to rotatethe shaft 5-andoperate Having thus fully described my invention, Iclaim:

In a guiding attachment for wheeled agricultural implements, thecombination with the seat bar of the implement having a bearing formedat its rear end, and a slanting brace bar extending downwardly from saidseat bar and formed with a bearing at its lower end in alinement withsaid bearing of said bar, of'a vertical shaft rotatively 'ournaled insaid bearings and'extending t erethrough, said shaft having a threadedupper end and a squared portion adjacent said threaded end and abovesaid seat bar, and having caster forks secured upon its lower end belowsaid brace bar bearing, a caster wheel journaled to rotate within saidforks,

a transverse lever having a central squared opening fitting about saidsquared portion of said shaft, a nut for engagement upon said '95threaded portion to hold said lever, an operating foot lever pivotallymounted centrally of its length upon said seat bar, and a pair ofconnecting rods extending between said operating lever and saidtransverse lever, parallel with and on each side of said seat bar,substantially as described.

In testimony whereof I affix my signature in'prosence of two witnesses.
